SD card driver for Freescale i.MX6 in Genode

I had talked about this earlier. We really need an i.MX6 reference
platform. Both the Wandboard or
the saberlite are good choices. I prefer the saberlite since it is the
official FS ref design.
I think a lot of us have variants of base_hw running on i.MX6. And F.OC and
seL4 also support it.

We do have a ref. i.MX6 tablet (production quality) coming next month that
will end up
as an additional ref. platform for us since we can actually run a
virtualized android on it.
I think the vendor plans to sell for for 300 USD. It has HAB enabled so we
can have a truly secure platform.

When it becomes stable and generally available, I would like to see it
adopted as a ref. platform
since it will be a usable android tablet running on genode (albeit with
slightly poor battery life
courtesy the i.MX6 !). I also want to convince the vendor to upgrade the
display. But it is a nice
aluminium chassis so does not look to shoddy.
